Brief description of the drawings
Fig. 1 is the structure diagram of an embodiment of the present invention;
Fig. 2 is the partial enlarged view of part A in Fig. 1.
Embodiment
The invention will be further described with specific embodiment below in conjunction with the accompanying drawings.
Embodiment:
With reference to Fig. 1, the high pressure hand-operated reversal valve with unloading function described in the present embodiment, including valve body 4, the valve body 4 Upper articulation have handle 1, the bottom side wall of the handle 1 is equipped with engaging lug, and the engaging lug passes through pin 12 and valve body 4 The link on top is hinged.
4 inner hollow of valve body, compression leg 2, main valve plug 6,10 and of main spool spring are equipped with its cavity successively from top to bottom Main valve silk plug 11.Sealing ring 3 is equipped between the inner wall of 4 inner cavity of outer wall and valve body of the compression leg 2, and the top of compression leg 2 is upward Stretch out the cavity of valve body 4.When handle 1 is rotated clockwise around pin 12, its bottom can mutually be touched with the top of compression leg 2.
The main valve plug 6 includes upper, middle and lower segment, its stage casing is the big pyramidal structure of top handle, between stage casing and hypomere Equipped with annular chuck;11 Screw assembly of main valve silk plug is equipped with the top of main valve silk plug 11 and inserted in the cavity bottom of valve body 4 Groove;The main spool spring 10 is sleeved on the hypomere outer wall of main valve plug 6, and top is withstood in annular chuck, and bottom is plugged in slot.
6 inner hollow of main valve plug, is equipped with internal valve mandril 5, the internal valve mandril 5 and main valve plug in the inner cavity of its epimere It is clearance fit between the cavity inner wall of 6 epimeres, and unilateral fit clearance is 0.06-0.1mm.The top of the internal valve mandril 5 The inner cavity of main valve plug 6 is stretched out upwards and contacts the bottom of compression leg 2.The lower part of 6 epimere of main valve plug is equipped with and 6 inner cavity of main valve plug The main valve plug oil leak hole 61 to connect.
The stage casing inner cavity of the main valve plug 6 and hypomere inner cavity up/down perforation are the identical cavity of internal diameter, and the cavity is interior Footpath is more than the internal diameter of 6 epimere inner cavity of main valve plug;Intracavitary is equipped with spherical interior valve core 7 in the stage casing of the main valve plug 6, described interior The bottom of valve mandril 5 contacts the top of interior valve core 7, and the bottom of the internal valve mandril 5 is pyramidal structure, as shown in Figure 2.
The top of 6 hypomere of main valve plug is equipped with the inner spool oil-through hole 62 to connect with 6 inner cavity of main valve plug, main valve plug 6 The bottom thread of hypomere inner cavity is equipped with internal valve silk plug 9;Interior valve spring 8 is equipped with the hypomere inner cavity of the main valve plug 6, it is described interior The top of valve spring 8 contacts the bottom of interior valve core 7, and bottom contacts internal valve silk plug 9.
The side wall at position corresponding with 6 epimere of main valve plug is equipped with fuel tank connector 41 on the valve body 4;The valve body 4 Oil inlet 43 and high-pressure work oil outlet 42 are symmetrically arranged with the side wall at upper position corresponding with 6 hypomere of main valve plug.
The principle of the present invention is summarized as follows:
During high-pressure work, high pressure oil enters valve body 4 from oil inlet 43, and main valve plug 6 and interior valve core 7 are made in high pressure oil at this time (high pressure oil is acted on interior valve core 7 by inner spool oil-through hole 62) makes primary valve be closed with interior valve port under, and high pressure oil is straight Connect and feed high-pressure work oil outlet 42.
After work, handle 1 is rotated clockwise;Compression leg 2 is depressed in the bottom of handle 1 first, and then compression leg 2 depresses internal valve Mandril 5, at this time, internal valve mandril 5 pull down interior valve core 7, open valve port, high pressure oil through interior valve port → internal valve mandril 5 with 6 fit clearances of main valve plug → main valve plug 61 → fuel tank of oil leak hole connector 41, with the slowly off-load of smaller flow.In this unloading process In, internal valve mandril 5 is gradually pushed, and internal valve mandril 5 remains unchanged at the beginning with 6 fit clearance of main valve plug, passes through internal valve The pyramidal structure of 5 bottom of mandril is gradually transitions larger gap, off-load flow also from keep smaller flow be gradually transitions compared with Big off-load flow.While being pressed completely into main valve plug 6 in 5 upper end of internal valve mandril, compression leg 2 produces main valve plug 6 downward Power, if hydraulic system is insufficient by interior 7 off-load of valve core at this time, working connection still maintains elevated pressures, and compression leg 2 will not be depressed Main valve plug 6 and then opening main valve, after interior 7 abundant off-load of valve core, when working connection pressure is smaller, compression leg 2 depresses main valve plug 6, And then open main valve.At this time, system big flow oil return box realizes oil circuit commutation control.
Consider from craftsmanship and action effect, the internal diameter size of 6 epimere inner cavity of main valve plug should take 4-6mm, the excessive hand of diameter Dynamic unloading process needs larger manual operation power, and the too small interior hole machined of diameter is more difficult.
Basic principle, main feature and the technological merit of the present invention has been shown and described above.The technical staff of the industry It should be appreciated that the present invention is not limited to the above embodiments, the above embodiments and description only describe the present invention Principle, without departing from the spirit and scope of the present invention, various changes and modifications of the present invention are possible, these change and Improvement all fall within the protetion scope of the claimed invention.The claimed scope of the invention is by appended claims and its equivalent Thing defines.
